MECHANISM FOR RELATIVE RECIPROCATION OF ROTARYv MEMBERS.

1'0 all whom it may concern: 7 v} Be it known that I, BRUonW. mimrnon, acitizen of the United States, residing at New York city, New York, haveinvented certain new and useful Improvements in Mechanism for RelativeReciprocation of Rotary Members, of which the following 1s aspecification.

My invention relates-to means for giving a longitudinalmovement to acrushing roll, and it consists in the features and combination andarrangement of parts hereinafter described and articularly pointed outin the appended claim D In the accompanying drawing Figure 1 1s acentral ,lon 'itudinal section through an apparatus embodying myinvention, parts being shown in section and broken away; Fig. 2 is asectional plan view of parts shown in Fig. 1.-

In these drawings, 1 indicates one of the crushing rolls and 2 itsshaft. With this roll is associated anbther roll, as is onetomary inthis art, between which rolls the material is to be crushed. The rollsare rotated in any suitable manner as by a fly wheel connected with theshaft of one roll, the other roll being driven throu h frictionalcontact from the first roll. n order to give one of the rolls alongitudinal or axial movement in relation to the other, I provide atthe end of the shaft of said roll a transverse shaft 3 mounted insuitable he rings in the frame at 4, as shown in Fig.

2-, 1nd this shaft is provided with an eccenti ortion 5 fitting in arecess in a block 6, which is secured to the end of the roll shaft, thesaid block being formed'in two sections-6 and 6, which embrace ribs 7extending circumferentially of the reduced end of said roll shaft.

The eccentric shaft 3 is rotated through a gear 8 thereon meshing with agear 9 on a shaft 10, which has its bearings in the frame at 11, Flg. 2,and this shaft is provided with a worm wheel 12 with which a worm 13meshes, said worm being connected with the reduced end of the roll shaftto rotate there- Speeification of Letters Patent.

Application filed November 25, 1911.

with. It will now be seen that, as the roll .shaft is rotated, the wormat the end thereof will, through the gearin described, rotate theeccentric shaft 3, and ing in. the forked or recessed lower portion ofthe block or box.6, 6', will give a longitudinal recipro t'qn'to theroll shaft and consequently to roll to displace it laterally or axiallyin relation to the companion roll. The worm is pinned to the roll shaft.

It will be understood by those skilled in the art that the longitudinalmovement of one roll is to prevent corrugation of the faces of the rollsbecause where rolls run without this relative longitudinal movement fora long time the ore runs more to one point than another and soon beginsto wear the shell more rapidly at that point. These corrugations willsoon decrease the capacity of the roll and prevent it from performingits proper function in grinding the material. having no longitudinalrelative movement it is possible to get OHlYOIlB-lltllf of the life ofthe shell. With the longitudinally l1lo\' able roll, however, the fullcapacity of the roll is derived and its life increased to the maximum.

I claim as my invention:

-In combination with a pair of rotary members, means for giving onemember a reciprocating movement axially, consisting of a worm on thesaid reciprocating member, two shafts extending transversely of themembers and beneath the same, a worm wheel on one of the said transverseshafts engaging the worm, an eccentric on the other transverse shaft, ablock operated by the eccentric and connected with the reciprocatingmember and earing between the two transverse shafts, substantially asdescribed.

In testimony whereof, I affix my signature in presence of two witnesses.
